13 Claims.

The present invention has for an object to provide `an apparatus andmethod of applying bands to articles Vsuch as cigars and the like.

, An object of the invention is to provide a mechanism capable ofcuttingout bands from a continuous strip of material and then applyingsaid bands about a cigar. A continuous strip or web of material may comedirectly from a printing or embossing mechanism, or may be provided in na web vupon a reel upon which the impressing or stamping has alreadybeen applied, and from the reel the web is periodically carried to a dieor punch where the band is cut out from the web or strip, and then meansare provided forsecuring l" ends thereof, transferring the same to aposition where it is applied about a cigar which is-presented thereto orwhich may be fed from a cigar making machine. n An object of theinvention is also to provide mechanism whereby a strip or web upon whichtwo or morev band patterns are provided may be utilized by merelyadjusting the reels holding the web so that the web may be passedthrough while removing adjacent bands impressed or printed thereon.

' It is an object of the invention to provide mechanism capable of usinga strip or web of material since bands oi the type operated upon consistonly of short pieces of relatively thin paper, and it is obvious that,if these pieces of paper were made separately and then stacked, theremoving of a single piece from such stack would be inconvenient and asimple apparatus would not be suiiicient. By utilizing a web or strip ofmaterial however, in accordance with'the present invention, the shortstrip or bandof paper or similar material is engaged while formed anddelivered directly to the cigars so that there is no necessity forstacking these short pieces of relatively thin paper and removing themindividually from the pile.

' It is a further object of the invention to provide an apparatus forcarrying out the process layer upon the plate over which the strip orweb of material is moving intermittentlydue to means cooperating with.perforations provided in the ,m strip. Preferably a die is provided inthe plate for an upper punch and the punched out strip of material ismoved from this position to an djacent position where finished cigarsare provided either by an endless conveyor or any other 55 suitabletransportingf means.

such cut out band, and while holding 'the twov the cutting mechanism asmany times as desired wherein `use is made preferably of a horizontalGermany November 2.2, 1932 It is a further object of the invention toprovide reciprocating means for moving the bands from the cutting outmechanism to the point at which the cigars are presented.

The main object of the invention is to simplify 5 the mechanism forapplying bands to cigars or similar articles.

With these and other objects in view which will become apparent as` thedescription proceeds, the invention consists in the method and locombination and arrangement of elements set forth below, claimed in theclaims and shown in the drawings, in which y Figure 1 is a partial frontelevation of a pre- Y ferred embodiment of the invention,

In the drawings the strip or web I upon which are. impressed, printed orstamped Vor embossed the coniiguration and outlines of the bands, isdrawn oi the reel 2 which is mounted upon the shaft 3. It' is obvious ofcourse that a printing or embossing mechanism may be provided and that aweb of paper may be fed to such printing v mechanism and then fed tothepresent'appara- 45 tus in place of 4the reel of already printed andembossed material. The shaft 3 is journalied upon the frame wall G'which is vertically positioned upon the machine table G.v The web I ofpaper or similar iiexibleV materialvis guided-by means of the guideroller 4 and the conveyor drum 5 over a stamping or punching table 6. Inorder to'prevent any slipping or sliding Kof the web during the advance,the drum 5 is provided with pins 5' which willengage in the holes l' 55furnished in the web I as shown particularly in Figures 8 and 9. 1

'I'he drum 5 is mounted upon an intermittently rotated shaft 1. 'I'heintermittent drive mechanism which will be described in greater detailhereafter, is so arranged that after each'intermittent movement of thedrum 5 the printed or embossed band upon the web I will arrive inposiconnected to the lever I3 and urges the roller 8 against the surfaceof the conveyor drum 5. From the roller. 3 the web I is led to a reel I2mounted upon the shaft I3. 'Ihe reel I2 is driven by a friction wheel I3whose shaft Iii is'xed upon the end of the oscillating lever I6.` 'I'helever I6 is urged by the spring I1 into contact at all times with thesurface of the reel I2.

Mounted upon the shaft l5 of the roller Il is a spur gear I1' whichengages with 'the spur gear I8 which in turn meshes with the spur gearI9 iournalled upon the lever I3.. The gear I9 rotates upon the shaft 23upon lever I6 and meshcs with the spur gear 52 mounted upon the shaft 1.The various gear wheelsabove mentioned are so arranged as to rotatt` thefriction roller Il and thereby Awind the strip or web I upon the reel I2after the same has been released by the durn 5.

The punch plate E is provided with a, recess 6' with which cooperatesthe reciprocating punch 2|. The shank 2| of the punch 2| is reciprocablevertically in the guide 22. A pin 2| is provided on the shank 2| and theforked cud E3' of the oscillating level` 23 engages therewith. The lever23 is journalled at 2 in the machine frame and is controlled by acontrol cam to be described below, whenever the printed or embossed bandupon the web arrives in the vicinity of the'upper punch 2|.`

Below the punch opening 5' there are provided two U-shaped supports orholders 25 which are attached to a slide 26. The oscillating lever 21has a forked end 21' which engages with a pin 25' upon the slide 25. Thevlever 21 is also controlled by a cam member to be describedhereinaftcr, so that the support may be moved into the extended positionshown by the dotted lines in Figure 2 and back again. 'I'he slide 23slides on the guide 23.

nallcdupon -tle supports 25. v'At the ends of the pivots 33 are fixedthe levers 3| and springs 32 engage the ends of the levers 3| so as toretain the flaps 23 under spring tension both in the extended positionshown upon Figure 5 and also in the position shown by dotted lines.Theupper punch 2| is provided with spring pins 33A which normally or inthe position of rest, project slightly below the surface of the punchAThese springactuated pins have a. particular .function which will bedescribed below and at the same time prevent the punched out band fromadhering to the lower punch surface upon the return of the punch.

The cigars Z which are to be banded are moved by means of the endlesschains 34 upon which are mounted the U-shaped supports S5 in which thecigars Z rest. The supports 35 imore on the guide plates 2I|| supportedin any desired manner in v the position shown.' AboveV and between thechains is located the apparatus 35' for delivering f and applying thebands to the cigars as shown more particularly in Figure 3. Thisapparatus comprises a slide- 31 which is arranged so as to be verticallyreciprocated upon a guide rod 38. Mounted `on the slide-are two levers39 having their pivot pointsatv-IU. These'levers -33 are urged by thetwo springs 4| to towards each other and the rollers 39'journalled uponthe levers I 39 are I orced against the guiderod 38; The lower end ofthe guide rod is curved as shown in Figure 3. l

At the free ends of the levers 33 are journalled 'the rollers. 332 overwhich a band 42 is placed and the ends thereof. are attached at 31' -tothe slide 31 with the interposed springs I3.

The apparatus is driven from the drive shaft 53 which is journallcd inthe bearing block 5l f attached tothe machine table G and this shaftcarries the loose belt pulley 55 and the fixed pulley 55. A bevel gear51 is xe'd to the shaft 53 and meshes with the bevel gear 53. The bevelgear 53 is mounted upon -the shaft 53 which `is journall'ed in thebearing blocks 53 and 5I attac-hed to the table G. Also mounted upon theshaft 53 is the crank lever 52 to which the crank rod 64 is pivotallyattached by means of the crank pin 53. The crank rod 53 is pivotallyconnected by the pivot pin 65 witlrthe double lever 66 to the end ofwhich is pivoted the pawl 53. The pawl 53 is urged by the spring 13 intothe teeth of the ratchet wheel 1I which is fixed upon the shaft 61. Theratchet: wheel 1| actuates the sprocket wheel 12 also mounted upon theshaft 61. The shaft 51 is mounted in the bearing eye 'I3 at one end andal. the other end in a bearing provided in the frame wall G'. Theconveyor chains 3l pass over the sprocket wheels 12 and also the guidewheels 13 which are journall'ed upon the pins 15. l

The shaft 53 also has mounted thereon the cam disks 15 and 11 which havecam grooves in which the rollers 13 and 13 are engaged. The rollers 18and v`|3 are rotatably mounted upon the double armed levers 33 and 3|whichare in turn pivctailymounted at 32 and 33. Pivotally secured to thefree ends of the levers 33 and 3| are the links 8l and 35. The linkmember 34 is pivotally secured to the arm 81 by the pivot pin 36 and thearm 81 is connected withthe lever 3l while the member 85 is connected tothe arm 39' the hollow shaft 33l with the lever I3.

The shaft 53 also has mountedthereon the bevel gear 33 which meshes withbevel gear 9| which is journalled upon the shaft 32 provided upon theframe wall G and in turn is connected with the spur gear 33 joumalledupon the rame shaft.' The spur gear 93 meshes with spur gear 94 which ismounted upon shaft 35 likewise provided in the frame wall G'. Connectedwith the gear 93 is the check disk' which carries the pin 91 whichcooperates with the Geneva starwhcel 33 which in turn is connected Withthe` spur gear 52 mounted upon the same-shaft 1.

There is also mounted uponthe shaft 53 the cam disk |33 with which thecam roller |32 mounted upon the control rod IIII cooperates. The controlrod IBI is pivoted at |33 to the twoarmed lever |84 and the forked endI3I' thereof engages the shaft 59. The double armed lever I 04 whichpivots about the axis |85 engages with its forked end |84' the pin |33which is provided sie upon the slide |01 which is in tum vertically,slidable-upon the frame' wall G. An arm |08 cam disk H0 with which theroller IH cooperates. The roller. II| is mounted upon the rod H2 whoseupper end is pivotally connected t0 vthe lever 23 by the pivot pin H3and the rod H2 is provided with a. forked end H2' at its other endvwhich` engages about the shaft 59. The

cam H4 controls the roller H5 which is mounted upon the lever 21 andthelever 21 is pivotally mounted by means of the pin I6 on the table G. IAn adhesive receptacle H8 is mounted upon the wall G' by means of thearm H1 and this receptacle is provided with a glue or paste swab I I9having a shank I9' passing through the bottom of the receptacle H8. Atthe lower end of the shank H9 there is a Ypivoted link member |20 whichis in tum pivotally connected to the double-armed lever I2| which inturn is pivotally mounted upon the wall G' at |22. I'he free end of thelever I2I has a roller |23 thereon which is controlled by a cam |24mounted upon the shaft The means for operating the previously mentionedaps 29 will now be described. The flaps 29 are controlled by means of alever |25 which -is pivotally mounted upon the shaft |26. At one end aroller |21 is'provided which is controlled by a cam |28 also mountedupon the shaft 59. The shaft |20 is mounted in the bearing eyes |29'uponthe wall G' and this shaft has secured thereto two arms |30 at the frontends -of which are provided the fingers |3|. There are also providedupon each arm |30 the upwardly extending pins |32.

The operation of the apparatus above described;-

is as follows. As the web or strip `I with the printed or. embossedbands thereon is carried by the intermittent movement of the drum belowthe punch 2|, the punch 2| is loweredand cuts' out the piece or band Zuin cooperation with the punch table 0. The punch 2| after severing theband from the strip or web carries the same into the holder 25 which isheld in readiness directly below the punch opening 8'. The punch 2|continues its downward movement to the bottom of the holder 25 as shownparticularly in Figure 5 So as to move the spring pins 33 back againsttheir springs. The punch 2| then begins to move upwardly and the ends ofthe band are maintained and held in the holders 25 by the springpins 33.As soon as the punch 2| has moved upwardly to about the dotted lineposition shown in Figure 5, the arms |30 are moved upwardly by theroller |21 as controlled by the cam |28. The pins |32 upon the arms |30will then contact the levers 3| and Jthereby swing theflaps 29 into thedotted line position as shown in Figure 5 and the ends of the flaps29iwill thereby come into contact with and hold the ends of the band Zuand retain the same while the punclf v2| continues its upward ascent.Then by means of the cam |24 the lever |2I is pivotcd againsii thespring means holding the roller |23 in contact with-the cam and the swabH9 which is no mally in the adhesive receptacle H8 is movedpwardly intothe lposition shown in Figure 5 by otte'd lines.

The swab H9 will thereby move into the depressions 25 provided upononeof the U-shaped sup- Vports 25 and will apply a dab of adhesive to thereleased by the flaps 29 the slide 31 descends so that the rollers 392and the band'42 positioned thereover will press the band upon the cigar.When the slide 3 1 continues its downward movement the flaps 29 areswung upwardly, which is accomplished due to the arms |30 describing adownward movement from their central position as shown by the full linesin Figure 2.

The fingers |3| will. then contact the ends of the levers 3| and swingthese levers 3| into the extended position of Figure 5 so that the ilapswill' release the ends of the band. As the slide 31 continues itsdownward movement, the rollers 392 will roll over the side portions of'the cigars. The Y function of the band or strip 42 is to make sure thatthe cigar band Zu is applied perfectly about the cigar Z. As soon as therollers 392 meet the finger 46 or/and roller 412, the lever 43' is swungto the right whereby one end of the strip or band is folded around thecigar. Then the lever.44 is moved to the'lei't while there is asimultaneous return movement oi the lever 43 and thereby the second endwhich has been provided with adhesive is pressed over the firstendiolded by the nger 48. As soon as the bandhas been applied around thecigar in the manner set forth, the lever 44 is again moved to the rightinto its initial position.

The endless chain 34 is then advanced and the next cigar is carried intothe vicinity of the apparatus 3B. While the apparatus 36 is operating incombination with the levers 43' and 44, the supports have again beencarried back by means of the slide 26 into the dotted line position ofFigure 2 for receiving a fresh band.

In the arrangement above described it is assumed that the adhesivereceptacle H8 is filled with an adhesive and that the band Zu isprovided with dabs of such adhesive at suitable points. It is of coursehowever obvious that during the printing, embossing or stamping of theweb with the outlines of the band, that these points can if desired beprovided with a fast drying adhesive which afterward need only bemoistened. In such a case of course the receptacle I I8 would be filledwith water,

If as shown in Figures 8 and 9 the strip is provided with two rows ofbands Zu then one row is first punched out of the web as shown uponFigure 8. The reel |2 is then changed for the empty rcel 2 and thelatter is then mounted upon the shaft I3 and the reel I2 upon the shaft3. In

v order to carry the second unpunched roll of bands While the web I inits rst passage through e the apparatus was engaged with the entireseries of perforations I', after the shifting ofthe shafts, only the twoelevated circulating rows of pins 5' as shown in Figure 4 will engage inthe two right rows of holes or pcrforations l' 'of the web. In

Y this case also the pins 5' will'engage with the periorations of thestrip in order. to actuate In this case the bands can lie longitudinallyof the web but as shown in Figure 10,` they may also be disposedtransversely thereof. In such case of course the conveyor drum 5 mustdescribe or make a correspondingly small advance movement and the webVmust be advanced at 'right angles to the advance movement oi thecigars.

In Figures 11 and 12 a modification is vshown in which the supports 25are not provided with aps 29. In` this modification the naps 2t arereplaced by suction nozzlesl |33 which are 4provided at both ends of theU-shapedholders 25 and to which a suction passage |34 is connected.. Itis of course obvious 'that' the mouthpiece |35 of the suction passagemusi be connected with some suction producing means such as a lfan orthe like. In such case aspccial control or drive is unnecessary becausewhile the band Zu is being applied on the cigar. the ends of the band Zuheld iirmly by the suction action are simply removed from the vicinityoi' the nozzle opening |33.
